Unfortunately, the thermal conductivity of the most commonly used insulation materials decreased only fractionally over the last decades. As a result, better building insulation equates to thicker building insulation. http://www.laboratory-journal.com/science/material-science/biopolymer-silica-aerogel Sun, 12 Feb 2017 13:35:00 +0000 There Is More to the Picture Than Meets the Eye http://www.laboratory-journal.com/science/chemistry-physics/there-more-picture-meets-eye For centuries diffraction was believed to set the fundamental limit to optical microscopy, so that structures below about half the wavelength of light cannot be resolved. In the last ten years, however, a variety of approaches has been developed, which enable optical imaging way beyond the classical diffraction limit [1]. http://www.laboratory-journal.com/science/chemistry-physics/there-more-picture-meets-eye Sun, 12 Feb 2017 12:29:00 +0000 Nanoporous Gold http://www.laboratory-journal.com/science/chemistry-physics/nanoporous-gold Arne Wittstock1, Gunther Wittstock2, Marcus Bäumer1,*   Nanoporous gold is a relatively new catalyst with great potential in heterogeneous gas and liquid phase catalysis and electrocatalysis. It is a sponge-like material with ligaments and pores in the range of a few 10 nm. Its catalytic properties are influenced by traces of a second metal and the nanostructure.   http://www.laboratory-journal.com/science/chemistry-physics/nanoporous-gold Sat, 11 Feb 2017 13:01:00 +0000 Universal Cutting Mill Pulverisette 19 – now available completely in stainless steel http://www.laboratory-journal.com/products/beater-mills/universal-cutting-mill-pulverisette-19-now-available-completely-stainless-stee Fritsch Cutting Mills are ideal for size reduction of soft to medium-hard, tough-elastic and fibrous materials.

However, a major drawback of these electrodes is lithium dendrite growth which can cause internal short circuits. Researchers from the Manthiram group at the University of Texas have now come up with a clever way to prevent dendrite growth: They simply wrapped the electrode in a Kimwipe paper!  http://www.laboratory-journal.com/news/scientific-news/wrapping-paper-lithium-anodes Thu, 26 Jan 2017 13:45:00 +0000 Personalized Offer Doubles Quitting Rate For Smokers http://www.laboratory-journal.com/news/scientific-news/personalized-offer-doubles-quitting-rate-smokers Offering smokers a taster session at an NHS Stop Smoking Service and explaining their personal risk of developing smoking-related diseases doubles their likelihood of attending a stop smoking course, according to a study in The Lancet. http://www.laboratory-journal.com/news/scientific-news/personalized-offer-doubles-quitting-rate-smokers Wed, 25 Jan 2017 10:51:00 +0000 Glioblastoma - Potential New Target for Treatment Found http://www.laboratory-journal.com/news/scientific-news/glioblastoma-potential-new-target-treatment-found Scientists have found a way to inhibit the growth of glioblastoma, a type of brain cancer with low survival rates, by targeting a protein that drives the growth of brain tumors, according to research from the Peter O’Donnell Jr. Brain Institute and Harold C.
